"Fig. .3, shows an enlargedsectionalview taken on the line 33 of Fig. 2. .Fig. at, shows a similarview taken on the line 4- l of Fig. 2.

. As here emb-odled. my improved device comprises an upright membergl0, of hollow tubular construction, .rotatively mounted in the support'll, attached tothe (1180 member 11",, adapted to enclose or cover the pit 14. The upright'member' extends upwardly therefrom in a-vertical position. The spherieal member, 12, of hollow transparent colcred material, preferably glass, or the llke,

representing the sun, is mounted on theupperiextended extremity of the upright member 10. I w

An electric motor 13, of the commercial type is mounted in the pit ll andis operatively connected by means-of electric wires to. an electric battery, or, any convenient source of electric. power, not illustrated in the accompanying drawings. The worm 15 is mounted. on the armature shaft of the electric motor 13, and meshes with-fa wormgear 16 mounted on the shaft 17, rotatively carried in the bracket 18, mounted in the pit 17. The bevel pinion 19 is mounted on the shaft 17," and meshes with the bevel gear 20, attached to the above mentioned upright member 10. The above described construction is such as will permit the electric motor 13 to rotate or revolve the spherical member 12. An electric light bulb 21, is mounted in a socket, of ordinary construction, positioned in the spherical member 12, and is connected by means of the electric light wires 22 and 23, extended through the upright member 10, and are connected to any convenient source of electric current, so as to permit the electric light bulb 21, to illuminate the spherical member 12.

The bevel gear 24 is attached, intermediate, tothe upright member and meshes with a bevel pinion 25, attachedto the tubular member 26, rotatively mounted in the bracket 27 attached to; and extendedl'from the arm 28; The tubular member 26,

is provided with an axial aperture, preferably of square cross-section, adaptedto slidably'receive the shaft 29, which is of simllar cross section to engage therein, so as to permit thetubular member. 26 when-rotated'to rotate the shaft 29. The shaft 29 is slidably mounted in the block 30, rotatively mounted in the bracket 31 attached to, and extended from the upright member 32. The shafts29 is slidably mounted in the block 33, rotatively mounted .in the bracket 34, attached to thecarriage 35. The bevel pinion 36, is attached to the shaft 29, and meshes with a bevel pinion 37, .rotatively mounted on the vertically extended element 38, of -thecarriage 35; The tubularmember 39, is. attached to the bevel pinion 37. The universal joint 40, such as commonly employed, is attached to the closed upper extremity of the tubular member 39, andsto the shaft 41, which extends upwardly therefrom." The spherical member 42, representing the earth, isattached to the extended extremity of thesliaft 41.: The member 43,

made in the form? of a frustum of a cone is of hollow construction and is attached to the carriage 38, and extends upwardly there-' from. i The shaft 41,-is positioned in the member 43,;and extends beyond the base of the fsaid member. The above described construction is such as will permit the above mentioned electrical motor to rotate the spherical member 42, and whichwill permit the member 43 to cause thespherical member 42. when rotated to travel, orrotate through acircular path, and assume the position designated by the reference numeral 42. It should be understood that the shaft 41 lies upon the edge portion of the member 43 and that as the shaft-is rotated it rolls thereon and is guided in a circular path by the circular contour of said member 43.

The arm 28 is attached, intermediate, the upright member 10, and extends outwardly therefrom in a horizontal direction. The bevel pinion 43, is provided with an axial aperture, of square cross section, to slidably accommodate the shaft 29 so as to permit the :shaft 29, when rotated to rotate the bevel pinion 13. The bevel pinion 44 meshes with the bevel pinion 43, and is attached to the shaft 45, rotatively mounted in the uprightmember 32. The bevel pinion elti is attached to the shaft l5. and meshes with the internal bevel gear Tl-T, supported by the disc member 11, and attached thereto. The above described construction is such as will support the arm 28, and the above described elements attached thereto, so as to permit the upright member 10 when rotated to swing the arm 28, in circi'ilar motion.

The support -18 is attached, at or near the extended extremity of the arm 27, and is provided with apertures, adapted to slidably receive the extended elements 49 and 50, ot

the :tork shaicd member 51. Jivotallv attached, as at 52, by a pin or the like, to the above mentioned carriage 35. The wheel 53 is rotatively mounted on the shaft 54 carried in the carriage 35. The wheel 53, is provided with flanged elements 55 and 56, adapted to engage the rail 5?, which is formed or bent oval. The above described construction is such as will permit the spherical member 42, to travel, or rotate in an oval path around the spherical member 12, as designated by the reference numeral It is understood that the hereinbc'torc described tubular member 26. and shaft 29, are also provided for this purpose. The gear "atios of the driving mechanism is preferably such as will cause the sphere 42 to rotate 864 times during each revolution 't-hereoi' about the sun member.

It is obvious that I have provided a. device which will clearly represent the movement and relative positions of the sun and earth.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the United States is as follows:

i. In a device at the class described a base couiprising a substantially horizontal platform, an ellipti'eal track mounted on said platform, a circular track comprising teeth inscribed in said elliptical track, a vertical shaft rotatively mounted on said platform and extending therehclow substant-ially at the center of the ellipse bounded by said track, a gear rigidly mounted on the lower end of said shaft and disposed below said platform, a motor disposed below said platform. driving mechanism operatively connected with said motor and with said gear for rotating the latter, an extensible arm attached at one end to said vertical shalt, a carriage comprising a. wheel mounted on said track on the other end of said extensible arm, said carriage being adapted to be revolved through an elliptical path, an inverted hollow conical member mounted on said carriage, a shaft mounted on said carriage extending within said conical member, a bevel gear rotatively mounted on said. shat't, a universal joint mounted on said bevel gear, a rod connected by said universal joint to said bevel gear and reclined. upon the edge. of said inverted hollow conical member, a sphere on the upper end of said rod and driving mechanisn'l operatively connected with the teeth of said circular path for rotating said sphere during the elliptical revolution thereof, said rod being adapted to roll on the edge portion of said conical member for guiding the sphere in a circular path at one and the same time.

In a device of the class described a base cinnprising a substantially horizontal platform, an elliptical track mounted on said platform, a carriage mounted on said track adapted to be guided throughout an elliptical revolution thereby, an inverted hollow conically formed member mounted on said carriage, a stub shaft mounted on said earriage and disposed within said hollow conical member, a universal joint rotatively mounted on said stub shalt, an arm connected to said universal shaft and extendii'lg upwardly through said conically formed member engaging the edge portion thereof, a sphere mounted on the upper end of said arm, and driving mechanism for simultane ously rotating said arm and the sphere thereon and revolving said carriage and sphere on said elliptical track, said arm being rolled on the edge of said conical member for guiding saidsphere throughout a circular path.

In testimony whereof I have atlixed my signature.
